**Mixic** · Brushed DC Motor Drivers · SOT-23-6

MX115 from Mixic, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | AIN | input | Input pin for channel A (forward signal); TTL/CMOS compatible, with VIH minimum 1.5 V and VIL maximum 0.7 V. |
| 2 | GND | power_in | Ground pin; decoupling capacitor of 10 uF or more should be placed close between VCC and GND. |
| 3 | BIN | input | Input pin for channel B (reverse signal); TTL/CMOS compatible, with VIH minimum 1.5 V and VIL maximum 0.7 V. |
| 4 | AOUT | output | Output pin for channel A driving the bidirectional motor; continuous output current 0.1 A at VCC = 12 V and peak current maximum 0.5 A. |
| 5 | BOUT | output | Output pin for channel B driving the bidirectional motor; continuous output current 0.1 A at VCC = 12 V and peak current maximum 0.5 A. |
| 6 | VCC | power_in | Supply voltage pin with recommended range 4.5 V to 15 V; a 10 uF or larger capacitor to GND is required to keep the supply stable. |
